Hello,We have a device that runs an stm32g0. I have a bootloader at the beginning of the flash and then 2 pages for config and the rest of the flash for the firmware. The bootloader basically checks if the two config pages are OK and then starts the ...
Hello,I'm currently working in a project with the Nucleo-L476RG board. Basically, I have a MEMS microphone (AN-000048) connected to the board. The microphone (I pretend to work in stereo mode) sends PDM data and I use the DFSDM module get the microp...
Hi there,this is my first post here. So be gentle with me ;)I been working on a project with STM32H757XIH6 for some time now, but without any success. This is already my 2nd prototype and costed me quite some $$ since it had to be a 8 layer PCB. The ...
Hi everyone,1, What are the acceptable buffer sizes for the DFSDM PDM mic configuration, give me some examples?2, Can I use ( int32_t buffer[4000] ) for the PDM buffer?3, How do I sync different sensors with the DFSDM PDM mic?
Hello,I'm a hobbyist and I'm working on a USB to 4xI2S (8 channels using the SAIs) using a stm32H7 MCU. I have a proof of concept working on a stm32F7 discovery board. I'm starting to look at the dedicated board.I understand that the USB peripheral n...
Hello,I'm using the nucleo-h743zi2 board.I am trying to use the USB OTG FS function.The .IOC file settings are as follows:USB_OTG_FS enabledMODE: DEVICE_ONLYVBUS: disableuncheck SOFI provided power through an external source and also swapped the D+ a...
I'm having some trouble performing a bank-swap on an STM32H745. The function works perfectly fine on an H743, but when porting over to the H745, it doesn't run the firmware that was swapped in.Firmware 1: prints "1.0". A button press will trigger a b...
Hi, I am unable to communicate via i2c with the TLV320AIC3104IRHBR chip, the bus response is always busy. I'm just using the STM's internal pullup, I check it on the oscilloscope and the pins are high but no communication happens. Below is my i2c con...
Hi Folks, I am using a STM32F070F6P6 microcontroller for a very basic/simple project to help learn the STM32 platform, etc.I am getting an error when I attempt to build my project that my code overflows FLASH memory by quite a bit. I did a test on a...
Posted on October 28, 2015 at 23:27Hi,In my design I'm using an external 24.576 MHz oscilator as I2S clock sourceAcoording to the reference manual, for 32 bit frames and MCLK output:FS = I2SxCLK / [(32*2)*((2*I2SDIV)+ODD)*4)] For Fs = 96 KHz, this g...
